What is Esculetin?

Chemical properties

YELLOWISH CRYSTALLINE POWDER

The Uses of Esculetin

In the presence of esculetin and HA14-1 (sc-205911) expression of the death receptor 4 (DR4) has been observed to be upregulated and extracellular-regulated kinase (ERK) to be activated. Other studies suggest that esculetin upregulates death receptor 5 (DR5) protein expression, and enhances TRAIL-induced apoptosis. It also inhibits the activity of 12-LO (12-lipoxygenase), and decreases leukotriene biosynthesis during 5-LO inhibition.

The Uses of Esculetin

antifungal, hepatoprotective, IL-1 inhibitor

The Uses of Esculetin

In filters for absorption of ultraviolet light.

What are the applications of Application

Esculetin is a hydroxyl radical and ROS scavenger that attenuates cellular oxidative stress

Definition

ChEBI: A hydroxycoumarin that is umbelliferone in which the hydrogen at position 6 is substituted by a hydroxy group. It is used in filters for absorption of ultraviolet light.

General Description

Esculetin is a derivative of coumarin, found in various plant species including Cichorium intybus (chicory), Bougainvillea spectabilis, Artemisia capillaris, etc and leaves of Citrus limonia (Rutaceae), Ceratostigma willmottianum, etc. It exhibits multiple pharmacological activities and is found to be a potent inhibitor of cyclooxygenase, 5-lipoxygenase, 12-lipoxygenase, catechol-O-methyl transferase, NADPH oxidase and xanthine oxidase enzymes.

Purification Methods

It forms prisms from AcOH, aqueous EtOH or aqueous MeOH, and provides leaflets on sublimation in a vacuum. [Kagan J Am Chem Soc 88 2617 1966, Marby et al. Phytochemistry 4 492 1965.] Esculin (the 6-glucoside) has m 215o(dec), [] D -41o (c 5, pyridine). [Beilstein 18 III/IV 1322, 18/3 V 202.]
